been remarked. "With our present knowledge, this affinity is
chiefly indicated by the occurrence of Indian natural orders or
genera, such as Stephanie,, Grei#ia$ Hijywcratea, hnpatiens,
Brucea,Zizyphus, Anoyeis&us, Blumea, J.a$minu.in3Torema; and
by the prevalence of those tribes of the larger or cosmopolitan
families which are especially Indian. This is the case with
Malvacete, Euyhorbiacca* Twlrinthacea, Leguminus&j Rubi-
acete, Asclqriadea, Accmthacece, Amaranthacea, Figs, and Or-
chidece. Few cases of specific identity arc known to us, but
we confidently believe that many will be foiuid to exist. • The
occurrence of Delphinium dasycaulon of Abyssinia in the
mountains of the Dckhmi is one instance; and we have little
doubt,, notwithstanding that M. Ach, liichard attempts to dis-
tinguish it, that Pterolobiwn lacerans is identical with the
Indian species. The Indian plants, Sponia velutina and Anti-
d&tma paHicufata, are also African; and the Celtis eriocarpa
of Dccaisnc appears identical with C. vesieulosa, Uochst., from
Abyssinia. Lastly, the absence of Oaks and Pines in both
countries i& a very strong point of resemblance.
There arc further examples of American gcuerji, and even
species, being found in India, but so few and scattered, com-
paratively, as .to render it unadvisablc to complicate our ar-
rangement 'by the introduction of an American *typc» As
conspicuous examples^ it will be sufficient to indicate Adeno~
cuulcn and Qxylaphus, of which genera the Indian species
were first described by Edgeworth; Podoyhyllum, the section
Styloixxllwti of Meconopm, and Liquidamlar. Ghietwn also
is a South American gcnxig, which lias not hitherto been found
in Africa; and Lardizabcda is interesting as a Chilian genus
of a small* order, the rest of which is entirely East Asiatic.
Monotropa uniflom and Brasenia are common to North Ame-
rica and India; and the curious little Mitreola panicufata,
Wall., is remarkable as being a native of India and Bmil,
and, so far as is. known, of no intermediate country**
